MICHAEL SPORLEDER, OF COLORADO CITY, COLORADO.

SAWING-MACHINE.

Application filed October 1, 1914.

To all whom it may concern:

Be it known that I, MICHAEL SroRLnonR, a citizen of the United States,residing at Colorado City, inthe county of El Paso and State ofColorado, have invented certain new and useful Improvements in Sawing-Machines, of which the following is a specification.

My invention relates to improvements in sawing machines, and an objectof my invention is the provision of means which can be instantly appliedto and operated by a lathe, such as used by jewelers or watch makers.

Another object is the provision of a sawing machine which will becapable of instant application or removal; which will be small andcompact in size to occupy a small space; and which will be simple andinexpensive in construction.

with these ends in view my invention consists of a sawing machineembodying novel features of construction and combination of parts forservice, substantially as shown, described and claimed.

Figure 1 is a side view of my sawing machine applied to a lathe, Fig. 2is a top plan view thereof, Fig. 3 is a view on line 33 of Fig. 1, Fig.4 is a view on line 44 of Fig. 1, Fig. 5 is an enlarged sectional viewof the means for guiding the saw carrying frame, and for holding thesupporting frame in position and, Figs. 6, 7, and 8 are detail views ofthe mechanism shown in Fig. 5.

Referring by numerals to the drawings in which similar numerals denotecorresponding parts in all of the views, the numeral 1 designates thelathe pedestal or support, 2 the table thereon, 3 the bearing bracket,on which is mounted the driving shaft 4; carry ing the graduated groovedpulley 6; and the clutch 7 to retain a suitable tool or implement 8.These parts are of the usual construction employed in a jewelers orwatch makers lathe and in connection with which. I prefer to use mysawing machine.

The table is provided with a longitudinally disposed opening or passage9, having formed thereon at its upper portion an en larged passage 10,entering another longitudinally disposed opening or passage 11, having abeveled upper face 16 formed therein. Fitting in the opening 10, is thebase 12, of the threaded sleeve 13, having a plurality of roundedcorners formed thereon and which is first inserted in the said open-Specification of Letters Patent.

ing 10, at one end of the table 2 and whenv at the desired location isthen turned into locking engagement with the slot or opening 10, bymeans of a suitable tool cooperating with the grooves 17 formed in theupper end of the sleeve 13. This seats the guide sleeve 13, in thetable, and the threaded sleeve 13, is engaged by the'threaded collar 14,having openings 15, to receive a tool for screwing the collar on thesleeve 13, thus substantially locking the said sleeve 13 and the frame18 to the said table 2 as clearly illustrated by Fig. 5 of theaccompanying drawings.

The construction described is clearly shown in Figs. 5, 6, 7, and 8, andprovides a guiding sleeve which is locked in the lathe table and aclamping collar surrounding said sleeve, which collar after beingproperly arranged will substantially clamp the said frame upon the lathetable.

The frame 18, is of L-shape having its vertical arm 18 provided with acollar 19, to receive the lower end of the upper L shaped section 20, ofthe frame. The upper section 20 and lower section 18, are securedtogether by a suitable fastening 21, and said upper section is providedwith a guide opening 22. In the sleeve 13, fits and is guided thevertical arm 23, of the lower saw carrying member whose horizontal arm23, is provided with a clamp 24, for securing the vertical arm 25, ofthe upper saw carrying member whose horizontal arm 25,

is provided at its free inner end with a threaded collar 26, forming theslot for the threaded lower end 27, of the sleeve 28. The sleeve 28, isguided in the opening 22, of the upper frame section and has a threadedbase 29, to be engaged by the adjusting bolt 30, which is operated bythe winged nut 31, and the adjusting bolt at its lower end is formedwith a head 32, receiving the jaws of the upper saw clamps 33. The uppersaw clamps 33, are thus carried by the adjusting bolt and the lower sawclamp 34,

is secured to the lower frame section at 35,

- in said opening, a

section is adjustably secured the collar 42, having an arm 43, connectedto one end 44, of the link 45, whose other end 46, is connected to thecrank 47 mounted on the driving shaft of the lathe.

The revolution of the. driving shaft' of the lathe imparts rotation tothe crank, which by reason Saw frame rapidly up and down and effects thesawing operation. I

The saw frame is properly retained, the saw can be easily applied andremoved ascan also the entire machine, and generally from every point ofview. the invention will prove efficient and practical.

I claim 1. In combination with the lathe table having an openingtherein, a guide fitting lower L-shaped frame member having itshorizontal arm clamped upon said guide, an upper L-shaped frame memberadjustably connected to the lower frame member, a lower saw frame memberadapted to'reciproca'te in said guide, an upper L-shaped saw framemember connected guided and of its connection moves the to said lowermember, a saw mounted in said saw frame members, and Connections withthe lathe for reciprocating the said saw frame. a

'2. In combination with the lathe table having an opening therein, aguide fitting in said opening, a lower lL-shaped frame memberhaving itshorizontal arm clamped upon said guide, an upper L-shaped frame memberadjustably connected to the lower frame member, a lower saw frame memberadapted to reciprocate in said per 'L-shaped saw frame member connectedto said lower member, asaw mounted in said saw frame members, a worktable support, a work table having adjustable connection with saidsupport, and connections with the lathe for reciprocating the said sawframe.

In testimony whereof I aflix my signature in presence of two witnesses.
